【摘要】 液压抓具因其独有的特点与优点，如动力性好、操作轻便、重量轻，在很多领域的应用越来越广泛，因此对于液压抓具的设计也提出了更高的要求。 本论文利用Matlab软件的优化工具箱，通过卧式六杆液压抓具的运动学、动力学分析，结合文中提出的液压抓具的4个评价指标，建立其结构优化的数学模型。并以BY9型液压抓具为例，进行结构优化。证明该优化模型是可靠的，在液压抓具结构优化中使用Matlab的优化工具箱是方便、快捷与实用的。对于液压抓具的性能评价，文中提出了4个评价指标，并利用它对两种国产抓具与FISKARS公司的四个系列的液压抓具进行了评价。更多还原

【Abstract】 Hydraulic grapple owns its special character and advantage .It means easier control and excellent performance .So it has been used more and more widely in many fields. Thus how to design a hydraulic grapple more quickly and more efficiently is a problem we have to solve.In this paper, a structure optimization model of horizontal six - bar linkage hydraulic grapple was built by means of its kinematics’ and dynamic analysis and combining with its evaluation indexes that was put forward by us. Even more we adopt MATLAB optimal toolbox to solve the model. On the basis of this, a concrete living example of BY9’s structure optimization was presented and arrived success. It prove that the model is reliable and practical and utilizing MATLAB in a Hydraulic grapple’ structure optimization is feasible.In this paper, four evaluation indexes was brought out to evalue the two kind of hydraulic grapples produced in domestic factory, and four series of that produced by FISKARS was appraised either.更多还原
